We're dividing 86430283 by 190 
The aim is to understand the frequency of 190 in 86430283.

On to step 1:
If we divide 8 by 190, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 190

Advancing to step 2:
The number 190 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 190

Moving on to step 3:
190 can be fit into 864 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 760 from 864 and we're left with 104.
Append the next digit (3) from the dividend to 104 and continue with: 1043 / 190

Moving on to step 4:
1043 divided by 190 is 5 with a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 950 away from 1043, we end up with 93.
Fetch the next digit (0) from the dividend, attach it to 93 and continue: 930 / 190

Moving on to step 5:
If we divide 930 by 190, we get 4 and a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 454.0
The remainder is 170 after subtracting 760 from 930.
Grab the next digit (2) from the dividend, add it to 170, then carry on: 1702 / 190

On to step 6:
When dividing 1702 by 190, we get 8 with a remainder of 182.
Use 8 as the next digit of our solution. 
Result so far: 4548.0
The remainder is 182 after subtracting 1520 from 1702.
Fetch the next digit (8) from the dividend, attach it to 182 and continue: 1828 / 190

Going ahead to step 7:
190 goes into 1828 9 times with a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 45489.0
If we take 1710 away from 1828, we end up with 118.
Append the next digit (3) from the dividend to 118 and continue with: 1183 / 190

Step 8:
The number 190 fits into 1183 6 times, leaving a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 454896.0
Deduct 1140 from 1183 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
If we divide 430 by 190, we get 2 and a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 454896.2
If we subtract 380 from 430, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
500 divided by 190 is 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 454896.22
If we take 380 away from 500, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 454896.22, and the remainder is 0.12.
